Short answer to your question: No.

Long answer: Look for the manufacturer's specifications. You should have received some sort of spec sheet with the alternator, as it is an aftermarket unit. If you, try the manufacturer's web site if you have the model number.

You can take it to any alternator shop and they will be able to test how many amps it is putting out, also a lot of the chain auto parts stores now have testing equipment, and I believe they will test the output for free. However if you take it to a alternator shop they can also tell you how many amps your car is pulling with your system on and all that good stuff.
